GENERAL INFORMATION

MAJOR COMPONENTS
Harvest Right Freeze Dryer

Power Switch: Located on the back of the freeze dryer (“0” is off, “I” is on).

Vacuum Chamber: This circular chamber includes a shelving unit for the trays.
The orange heating pads on the shelving unit should face down.

Trays: These hold the material to be freeze-dried. Do not overload trays or batch times will be extra long.

Power and Display: The freeze dryer is powered by plugging the power cord into the back of the freeze dryer (one receptacle is for the power cord and one is for powering the vacuum pump) and a functioning 110-volt power outlet. A dedicated 20 amp circuit is required for large freeze dryers.

Vacuum Pump: Connect the vacuum hose to the connection on the side of the freeze dryer and to the appropriate fitting on the vacuum pump. The vacuum hose should be tight. Be sure to hand tighten both ends of the vacuum hose to properly connect the freeze dryer to the vacuum pump. Plug the vacuum pump power cord into the receptacle on the back panel of the freeze dryer. Make sure to add the right amount of oil to the vacuum pump as specified in the manufacturer’s instructions (See the image on Page 5, Figure 1). Make sure the vacuum pump is “on/ off” switch is set to the “ON” position (“O” is off, “I” is on). It will not receive power until the freeze dryer completes the circuit at the appropriate time in the freeze-drying process.

Oil Demister: The black cylinder is attached to the top of the vacuum pump.

Drain Line: This is a clear tube, located on the side, toward the bottom back of the freeze dryer. This tube should be un-coiled and the open end placed in a drain or a 5-gallon bucket (or similar container) to collect the water removed during freeze-drying (collects as ice on the sides of the vacuum chamber). Don’t open the drain valve with the open end of the clear hose in water or the water will be sucked into the freeze dryer.

Before you start a freeze-drying cycle make sure the valve on the drain tube is closed. The small handle on the valve should be perpendicular to the tube (See Figure 3, page 6).

IMPORTANT SAFEGUARDS

Safety INFORMATION
Read all instructions carefully before using your Harvest Right Freeze Dryer.
Following these instructions will help prevent injuries, and damage to the freeze dryer, and will ensure that you have the best possible experience with your freeze dryer.
Save these instructions.
When using this appliance always exercise basic safety precautions, including the following:

  • Use this product only for its intended purpose as instructed in this Owner’s Manual.
    WARNING Do not use an extension cord when plugging your freeze dryer into your power source. Most extension cords cannot handle a sufficient draw of power and may melt or deform causing a fire or other damage.

  • Do not use surge protectors or plug your freeze dryer into a GFI outlet.
    These sources are very sensitive and may cause your freeze dryer to unnecessarily trip the power breaker.

  • Do not allow children to climb, stand on the freeze dryer, or hang on the door or shelves. They could damage the freeze dryer and injure themselves.

  • After your freeze dryer is in operation, do not touch the cold surfaces during the freezing cycle, particularly when hands are damp or wet. The skin may adhere to these extremely cold surfaces.

  • Do not store or use gasoline or other flammable vapors and liquids in the vicinity of the freeze dryer.

  • Keep fingers out of “pinch point areas”. Clearances between the doors and the closing mechanism are necessarily small. Be careful closing doors when children are in the area.

  • Unplug your freeze dryer before cleaning or making repairs. We strongly advise that service be done by a qualified individual.

  • Refrigerants: All refrigeration products contain refrigerants, which under federal law must be removed prior to product disposal. If you choose to dispose of an old refrigeration product, check with the company handling the disposal about what to do.

  • This appliance is not intended for use by small children or infirm persons without capable, adult supervision. Children should be supervised when using the appliance.

  • Do not use a wet or damp cloth when cleaning the plug at the end of the power cord. Remove any dust or foreign matter from the power plug pins. A dirty power plug can increase the risk of fire.

  • Do not block vent air holes. If the air holes are blocked, the freeze dryer could overheat. Keep vents clean.

  • Never unplug your freeze dryer by pulling on the power cord. Always grip the power plug firmly and pull it straight out from the outlet. Pulling on the power cord could cause a fire and/or electric shock. A damaged power cord must be replaced by the manufacturer, a certified service agent or qualified certified service personnel.

  • Use caution when putting your hands under the appliance. Any sharp edges may cause personal injury.

  • Do not insert the power plug with wet hands. It may cause electric shock. In general, power consumption will average between 9-11 amps of power and spike near 16 amps. Usage of a dedicated 20 amp circuit will prevent power outages and allow for proper freeze-drying.

  • Do not defrost your freeze dryer with a blow dryer or other heating device.
    There is a thermal cutoff that protects the machine and the material inside the chamber from overheating. If the thermal cutoff gets too hot, it will eliminate all power to your shelf heaters and will need to be replaced with appropriate parts.

NEVER OPERATE THE FREEZE DRYER IF IT APPEARS DAMAGED
If it is dropped or damaged in any way, call Harvest Right Customer Support immediately at 1.800.865.5584 for examination, repair, electrical or mechanical adjustment, or possible replacement of parts.

BE CAREFUL ABOUT WHAT YOU PUT IN YOUR FREEZE DRYER
The freeze dryer is designed to freeze-dry materials or products that contain water. Freeze drying other materials may void the warranty and could damage the freeze dryer.

THE VACUUM PUMP RUNS HOT
Use caution when running your freeze dryer as the external vacuum pump can reach 160˚F during operation. Keep your vacuum pump out of the reach of children as it may cause injury if touched. Your vacuum pump is built to run hot. Use care and caution in order to prevent injury.

RECOMMENDED OPERATING TEMPERATURES
Your Harvest Right Freeze Dryer is designed to work in a wide variety of environmental temperatures, but extreme heat and cold will affect performance.
The recommended temperature range for operation is 35-90°F. The most efficient temperature range is between 45-75°F. Although safe, operating your freeze dryer in temperatures above 90˚F will increase batch times and may have an adverse effect on the condensing unit (freezer). As the temperature rises where your freeze dryer operates, so does the length of time it takes to finish. This happens because with hotter operating temperatures it is harder to reach the extreme cold required for freeze-drying. When running your freeze dryer in temperatures higher than 90˚F, place a small fan in a location where it can blow air on the vacuum pump. This will help the pump run more efficiently and may increase the life of the vacuum pump.

For example, a batch that normally takes 24 hours to finish in a 75°F environment could take over 40 hours to complete in hot temperatures.

FREEZE DRYER ASSEMBLY

assembly instructions

Wait 24 hours before running your freeze dryer in order to facilitate the proper settling of the refrigerant within the condensing unit.

  1. Once unpacked, place the freeze dryer on a level, stable surface. The ideal location for operating your freeze dryer is a cool, dry, clean location. Dirty air will clog the cooling fins in the condensing coil and reduce the life and efficiency of the refrigeration system. Ensure that the freeze dryer side vents are unobstructed to allow proper airflow during use.

  2. Check the rubber door gasket to make sure it is clean.

  3. Make sure the inside of the acrylic door is clean. Use an only dry cotton cloth and warm water, no cleaners.

  4. Put oil in your vacuum pump by removing the red cap. (If you have one of our bright green Premier oil pumps, you need to unscrew the black oil demister on top of the pump). Fill your vacuum pump to the center of the sight glass and replace the cap (See Figure 1).

  5. Connect the hose to the freeze dryer (See Figure 2) and to the vacuum pump and tighten. Hand tightening is generally adequate, but you may gently use pliers or vice grips, as required. Do not over-tighten. Do not add any additional Teflon tape, or any type of adhesive, when installing the vacuum hose. Doing this usually creates a vacuum leak
    because it interferes with the O-ring in the hose. Instructions for connecting the oil-free pump are on page 15.

  6. Connect the freeze dryer power cord to the receptacle on the rear panel of the freeze dryer and to a 110 outlet. A dedicated 20 amp circuit is required for large freeze dryers.

  7. Connect the vacuum pump power cord to the receptacle on the rear panel of the freeze dryer.

  8. Make sure the power switch on the vacuum pump is in the “ON” position. (“O” is off, “I” is on). The power button is located on the back of the oil vacuum pump.

  9. Insert the black insulator door pad into the door opening, past the rubber gasket, to plug the gap between the shelving unit and the back edge of the gasket. Make sure your shelving unit is pulled forward close to the rubber door gasket so the insulator door pad will snugly fit between the door and the shelf. Do not allow the door pad to get caught between the door and the rubber gasket.

  10. Secure the door latch to create a good seal. The door latch is a two-staged handle. Stage 1 latches the door and stage 2 compresses the door to the rubber gasket. Turn the handle as far to the right as possible. Do not apply too much force. Don’t break the door latch. 

  11. Make sure to close the drain valve on the freeze dryer, located on the side, toward the bottom back of your freeze dryer. When in the closed position, the small handle on the valve should be perpendicular to the direction of the drain tube (See Figure 3). If the drain valve is not closed, there will be a vacuum leak which could damage your vacuum pump and void the vacuum pump warranty. Be sure to place the open end in a 5-gallon bucket, drain, or similar container, to collect the water that is removed during the freeze-drying defrost process. Be sure to keep the hose out of the water, as it will suck water into the chamber.

  12. Ensure that the acrylic door makes contact with the rubber gasket by examining the door in the fully closed position. You will see a thin line in the middle of the gasket (that goes partially around the gasket) as it presses up against the door. When the pump turns on, make sure the door fully seals against the gasket.

  13. As described in previous steps, it is your responsibility to make sure the door is closed properly, the drain valve is closed, and the hose connecting the vacuum pump to the freeze dryer is connected. The successful functioning of the vacuum pump depends on these steps being performed properly.

  14. Turn on the freeze dryer by pressing the switch to the “ON” position (“O” is off, “I” is on). The On/Off switch is located on the back of the freeze dryer. Next, in order to perform a quick test and ensure that your freeze dryer is set up properly, complete the following steps. To accomplish this task, your freeze dryer chamber must be free of any damp or wet material such as water or condensation. It needs to be completely dry.

  15. Press “Start” on the touchscreen.

  16.  The next screen will prompt you to close the drain valve. Do this and press “Continue”. You will need to press the leaf in the top left corner to turn the vacuum pump on. When the vacuum pump first turns on, the display will read“>2500 mTorr”. Within 10 to 15 minutes the pressure will reduce until it is below 500 mTorr. When this occurs, your test is successful. Turn off your freeze dryer and open the drain valve. This will release the pressure and allow the door to be opened. You are ready to start your first batch.
    If 500 mTorr or lower is not reached, check for air leaks and repeat the test.
    1. Door must be properly closed.
    2. Hose connecting the vacuum pump to the freeze dryer should be securely tightened on both ends.
    3. Drain valve must be closed.
    For a tutorial, go to: http://bit.ly/DryChamber (Dry Chamber Test Tutorial).
    If you are unable to successfully complete this test because the vacuum pressure won’t go below 500 mTorr, please call Customer Support: 800-865-5584.

  17. Before using your freeze dryer, please note the following:
    New freeze dryers need to have a one-batch burn-in period. That means you should fill the freeze dryer with moist bread slices and freeze dry it. After the bread is finished, test it for dryness and throw it away. This way you can make sure your freeze dryer is working properly and it will help remove any manufacturing “new car” type smell.

  18. Prepare the material that you want to freeze dry and place it on the trays, one layer thick so that it can be uniformly warmed by the shelving unit. The product that is prepared in uniform thickness will dry quicker.

  19. Material that is pre-frozen should be placed in the freeze dryer after it is cooled.
    To accomplish this, power on your freeze dryer. Once you press “START”, the unit will prompt you to close the drain valve. (In the closed position, the drain valve is perpendicular to the hose. See Figure 3, Page 6.) Do so, then press “CONTINUE”. The unit will start “FREEZING”. Allow the chamber to cool for 30 minutes.
    If your material is not pre-frozen, after pressing “START”, you will be prompted to close the drain valve. (In the closed position, the drain valve is perpendicular to the hose. See Figure 3, Page 6.) Do so and press “Continue”. The unit will start “FREEZING”.

  20. Place trays in the shelving unit inside the freeze dryer. Insert insulator pad. Close the acrylic door and turn the door latch clockwise as far as it will go, compressing the door against the rubber gasket. Visually check to make sure the door is sealed properly to the gasket. If the door is not latched tight, there will be a vacuum leak.
    From then on, everything is automatic. Just remove the trays when the process beeps to notify you that it is complete. At the end of the process, follow the prompts on the screen.

  21. When the process is complete press “Continue” on the “Ready to Finish” screen. You will then be prompted to “Open the drain valve to vent”. Before doing so, pull the drain hose out of the bucket and/or check to ensure the bucket is completely empty of any water. Opening the drain valve vents the vacuum pressure. Then the door may be opened, the insulator door pad removed, and the trays removed. Check the material thoroughly to make sure it is dry. If you find that there is still moisture in the material, simply press “More Dry Time” and allow the freeze dryer to finish drying. Otherwise, you can remove the trays, ensure the drain hose is properly placed for draining, and press “Defrost”.

  22. Immediately package your freeze-dried material so that it doesn’t rehydrate from the natural humidity in the air. When packaging material, you can use cans, Mylar bags, and glass jars. Always use an appropriate oxygen absorber.

  23. Make sure all of the ice and water is removed from the vacuum chamber before starting a new batch. Pressing the “Defrost” button turns on the heaters in the shelving unit and accelerates the melting of the ice. Ambient air can also melt the ice over time.

using the “customize” settings
Power on your freeze dryer. Press “Customize” on the touch screen. This screen allows adjustment of the temperature for the warming elements inside your freeze dryer. The default setting is 55°F but may be adjusted. On this screen, you will notice a button that allows you to “Adjust Cycle Times”.
This screen allows you to adjust the “Final Dry” time. To temporarily adjust this time, press the arrows up to increase the time (the factory setting of 10 hours is sufficient for most items). You will see the displayed time change in 15-minute increments. Press “Done” to begin your custom batch. You will then be reminded to “Please close the drain valve”. Pressing “Continue” starts the “Freezing” cycle. The word “Freezing…” will be displayed on the touch screen.

A CLOSED SYSTEM

WHAT IS A CLOSED SYSTEM
In order to freeze-dry items, your machine will use a vacuum pump that removes the air and creates a vacuum environment. In order to achieve adequate vacuum pressure, it is VERY IMPORTANT to ensure that all valves are closed tightly. If there is a leak somewhere in the system, the freeze-drying process will not occur.

WARNING: You may think there is not an air leak in your machine because the door will not open (a sign that you are pulling a vacuum). However, it is possible to achieve less than suitable vacuum pressure, yet have enough vacuum to hold the door closed. Initially, >2500 is displayed. Within 10-20 minutes you should see the number 2500 begin to decrease. Drying occurs when the vacuum pressure descends to 500 mTorr (also displayed). If after 30 minutes 500 mTorr has not been reached, checking for leaks is a logical next step. Make sure the drain valve is closed and the door gasket is sealing properly (clean the gasket in warm water, let dry, and reinstall—do not wipe dry because lint may prevent a good seal).

While every precaution has been made to ensure that there are no leak points in your vacuum system, a situation could arise where there is a leak point. It is important to check the following possible leak spots in order to achieve optimal freeze-drying.

POSSIBLE LEAK POINTS ON THE VACUUM PUMP

  • Vacuum pump hose connections
  • Vacuum pump oil is contaminated
  • The vacuum pump oil level is too low
  • Gaskets in the vacuum hose are damaged
    For additional information about your vacuum pump, review the instruction manual that came with your vacuum pump.

POSSIBLE LEAK POINTS ON THE FREEZE DRYER

  • The drain valve is open
  • Vacuum pump hose not connected properly or tightly
  • Door not properly shut (2 stages of closing, latch, and compression against gasket)
  • The door gasket is not clean inside and out
  • Door needs adjustment

CARE AND CLEANING

OIL VACUUM PUMP MAINTENANCE
We recommend you change and filter your oil every 4-5 batches (for the standard pump) or every 20-30 batches (for the Premier pump) — or sooner if the oil is cloudy — in order to ensure high vacuum performance and to increase the life of your vacuum pump.

For optimum performance of your vacuum pump DO NOT reduce the freeze time or bypass the freezing cycle of your freeze dryer! For shorter freezing cycles you may pre-freeze the products until they are frozen solid before placing them in the freeze dryer but STILL DO NOT bypass the freezing cycle of your freeze dryer! Freeze drying products that have even a little non-solid moisture in them will reduce the performance and the life of the vacuum pump

DO NOT overload the trays in the freeze dryer. Too much product will produce too much-evaporated moisture which may exceed the ice capacity inside the vacuum chamber and cause the vacuum pump to suck in the excess moisture. This may affect the performance and shorten the life of the vacuum pump.

Oil Change

  1. Turn off the vacuum pump.

  2. Locate the drain valve for the oil reservoir located at the bottom, front of the pump.
    (See Figure 4). Make sure it extends past the edge of the table or cart.

  3. Place your oil filter beneath the drain valve to collect the oil.

  4. Open the valve.

  5. Drain the oil from the vacuum pump into your filter.

  6. Elevate the back of the pump slightly and drain the remaining oil from the drain valve. Once all the oil is drained, close the drain valve. When draining the oil out of the Premier pump, do not tilt the pump too much as that will cause oil to fill the oil demister.

  7. Using new or filtered oil, refill the oil reservoir to the appropriate level. (See the image on page 5, Figure 1)

  8. Turn the vacuum pump switch back on.

Oil Filtration

  1. Standard Pump: Approximately every 4-5 batches; Premier Pump: Approximately every 20-30 batches. Preferably when the oil is still warm, place the oil filter below the oil reservoir drain valve.
  2. Open the oil reservoir drain valve and allow oil to drain into your oil filter. Assure all of the oil comes out by lifting the rear of the vacuum pump slightly. When draining the oil out of the Premier pump, do not tilt the pump too much as that will cause oil to fill the oil demister.
  3. Wait for the oil to filter through your filtration system (this could take a couple of hours).
  4. Remove the water from the oil by pouring off the oil and discarding the water. Do not pour the water back into the vacuum pump.
  5. Pour the filtered (or new) oil into your vacuum pump.
  6. Start your freeze dryer.

How do I know that my filtered oil is clean for use?
The best indications for cleanliness are as follows:

  • Oil has clarity (color may be yellow or amber and still be clear)
  • Your vacuum pump achieves a pressure (mTorr) suitable for freeze-drying

How do I know when I need to replace my oil filter?

  • Oil won’t drain through filter (happens over time as debris builds up)
  • Oil isn’t cleaning well

How do I replace my oil filter?
Replace the paper filter (coffee filter) and batting inside the filter, or, purchase a new filter from Harvest Right. The filter material inside the oil filter can be replaced every 20 to 30 batches (or sooner if the filter looks really dirty).

The bottom of the filter material is a common coffee filter that may be purchased in any grocery store. The material above the coffee filter is quilt batting and can be purchased in most hobby stores and department stores (Walmart, Target, etc.). The quilt batting should be packed tightly into the filter jar.

CLEANING THE INTERIOR AND EXTERIOR OF YOUR FREEZE DRYER
Interior: First unplug your freeze dryer from the wall. Clean the vacuum chamber and shelves with a mild detergent and then wipe dry with a soft cloth. Remove shelves for a thorough cleaning. In order to remove the shelves, you will need to take off the black rubber gasket that the door seals against. Gently pull out the shelf. Then disconnect the cable. Once the red tab is unlocked, press the black tab down and pull the two pieces apart. When finished cleaning, ensure that the shelves and chamber are dry. Next, reconnect the power line to the shelving unit.

It is important to clean the chamber and the shelf on a regular basis. It is necessary to do this by hand. You can put the shelf in a large sink and wash it with dish soap, brushes, and rags; however, a dishwasher can get so hot that it will melt the glue and cause the heating pads to loosen and fall off.
Using a dishwasher to wash shelves will void the freeze dryer warranty.
Exterior: The outer door, handle, and cabinet surfaces should be cleaned with warm water and a mild detergent and then wiped dry with a soft cloth.

CLEANING CAUTIONS
Do not use stiff-bristled brushes or abrasive cloths/pads to clean the freeze dryer, interior or exterior, as this will dull or scratch the surface.
Do not use Benzene, Thinner, or Clorox for cleaning. They may damage the surface of the appliance and may even cause fires.

MOVING OR LONG ABSENCES
If you have a long vacation planned, empty the freeze dryer and keep it turned off.
Wipe any moisture from the inside and leave the chamber door open to keep odor and mold from developing. Drain the pump and fill it with fresh oil.

TROUBLESHOOTING

FREQUENTLY ASKED QUESTIONS

Why has the freeze dryer been running for over 46 hours and the process is not complete?

There are a number of factors that can contribute to longer cycle times. Some of which may be a combination of the following:

  1. Some items are more challenging to freeze dry than others. Because of their cellular structure and moisture content, some materials with high amounts of liquid may take longer to freeze dry. The freeze dryer is measuring the removal and moisture and knows when the process is complete.
  2. There is so much water in the material being dried that the condensed ice on the walls of the chamber has begun to encroach on the trays. While rare, if this occurs, the freeze dryer cannot recognize that the process is complete because it will sublimate the ice that is coming onto the trays. If this happens, remove the trays and put them in the freezer, defrost the ice in the freeze dryer, put the trays back in the freeze dryer, and allow it to finish the process.
  3. The vacuum pump oil should be changed and filtered every 4-5 batches (sooner if the oil is cloudy). As the oil in your pump gets older, the cycle time for food may increase.
  4. The freeze dryer is working properly if, during the drying portion of the freeze-drying cycle, the vacuum is reading between 100-900 more.

After my freeze-dry cycle finished and I released the drain valve, water came rushing into my vacuum chamber. What happened?

Make sure to empty the container that your freeze dryer drains into. If the drain hose is sitting in water when the vacuum is released by opening the drain valve, water will suck through the drain hose and into the freeze dryer vacuum chamber like a giant straw.

We had oil spray out of our vacuum pump, what is happening?

  1. It is likely that air is leaking into your freeze dryer chamber (or the vacuum pump is over-filled). This can happen if the drain valve is accidentally left open, the door isn’t clean/aligned properly, the door seal isn’t clean, or the vacuum hose is not completely tight on both ends. It can also occur if all of the caps/ fittings on the pump aren’t tight. These are the most common reasons for an oil spray.
  2. The oil level is too high. It may have been over-filled or because of water vapor coming through the vacuum hose and condensing as a liquid into the oil (it is important to drain this water out of your vacuum pump and discard it so that you can preserve the life of your oil as well as prevent an oil spray).

When the process is complete, sometimes the shelves are warm and sometimes they are cold. Why?

The final step of the freeze-drying process is a post-dry. The shelf heaters will turn off for the last hour of the freeze-drying process. This is so the trays are not hot when pulled out. When the process finishes, the heaters turn off and the vacuum pump turns off. The condensing unit (freezer) stays on to make sure the ice does not melt and rehydrate the product being freeze-dried.

If the product is removed immediately after the process is completed, the trays may be hot from the heaters that are on during post dry. If you take the product out a few minutes after it beeps, the trays will be cold. If you don’t get the material out within a few hours, the trays will be very cold. Always remove the trays with a glove because they will either be warm or cold.

Although the trays are at -40°F, because there is no water in the product to freeze and make it cold, the material will seem to be at room temperature on -40°F trays.

Test that the product is 100% complete by breaking the thickest piece. If it is cold or wet in the middle, there may be a bit of moisture left in it, and it should be put through the vacuum-dry cycle one more time.

I packaged my material and it was very dry when it came out, but now it is not dry. Why?

  1. Properly packaging the freeze-dried material is vital. It is important to promptly package your freeze-dried product. When packaging, you can use Mylar bags (in order to seal thoroughly, we recommend you seal the bags twice to be safe), #10 cans, or mason jars. Always use the appropriate oxygen absorber. To ensure long shelf life, store in a cool, dry location.
  2. Occasionally, all of the product will be perfectly freeze-dried with the exception of a couple of pieces. This can happen if you cut a few pieces of your product much thicker than the rest. If packaged, one wet piece will rehydrate and ruin the whole batch. When a batch is complete, it is a good idea to break the thickest piece on your trays in half and test it in order to be sure that the product has completed the drying process. If you find that the material is not completely dry, simply put it back in the freeze dryer
    and press “More Dry Time” to get right back into the vacuum pump/drying portion of the freeze-dry cycle. The freeze dryer will then finish the pieces that weren’t quite complete.

PUMP ISN’T TURNING ON DURING THE DRY CYCLE:
Make sure your pump is plugged into the back of the freeze dryer and is switched to the “ON” position. The freeze dryer controls the pump turning on and off, but it cannot do so unless the pump is switched on (the switch is located on the back of the pump) and plugged into the freeze dryer.

OIL-FREE VACUUM PUMP

Oil-Free Vacuum Pump set up

  1. Connect the vacuum hose to the vacuum pump and to the freeze dryer, and tighten (See Figure 5). Do not add any additional Teflon tape, or any type of adhesive, when
    installing the vacuum hose. Doing this almost always creates a vacuum leak.

  2. Plug the vacuum pump power cord into the receptacle on the back of the freeze dryer.

  3. Make sure the power switch on the vacuum pump is switched on.

For optimum performance of your vacuum pump DO NOT reduce the freeze time or bypass the freezing cycle of your freeze dryer! For shorter freezing cycles you may pre-freeze the products until they are frozen solid before placing them in the freeze dryer but STILL DO NOT bypass the freezing cycle of your freeze dryer! Freeze drying products that have even a little non-solid moisture in them will reduce the performance and the life of the vacuum pump.

DO NOT overload the trays in the freeze dryer. Too much product will produce too much-evaporated moisture which may exceed the ice capacity inside the vacuum chamber and cause the vacuum pump to suck in the excess moisture. This may affect the performance and shorten the life of the vacuum pump.

PREMIER VACUUM PUMP

  • When using, please be sure that the gas ballast switch is open* (Figure 7). It is really important that you operate the Premier Oil Pump with the gas ballast valve open. If the pump is used incorrectly with the gas ballast closed, you will ruin it.

  • If the oil remains clear, you can change it every 20-30 batches. If the oil gets cloudy, or looks dirty, change it immediately.

  • To fill or add oil to the Premier Oil Pump, unscrew the oil demister (See Figure 6) and use a funnel to pour the oil into the opening (See Figure 8). Fill to the appropriate level shown on the sight glass (see Figure 9, halfway between MIN and MAX). When finished, replace the oil demister.

  • If you do not open the gas ballast the oil is only good for 4 to 5 batches, then it needs to be replaced.

PACKAGING

Packaging Freeze-Dried Material: Instructions

  •  Fill the Mylar bags
  • Add an oxygen absorber
  • Seal immediately on the highest setting (8) of your Harvest Right sealer

The following are things to consider:

  • When you open a pouch of oxygen absorbers, they need to be used immediately. Therefore, you should not open your oxygen absorbers until your freeze-dried material is in the bags and is ready to be sealed.

  • Immediately reseal your bag of oxygen absorbers. And, immediately seal your bags that have the absorbers in them. The setting for sealing the bags of oxygen absorbers is less than for the Mylar bags. To seal bags of oxygen absorbers use setting 5 on your Harvest Right sealer.

  • A chemical reaction takes place when the oxygen absorber is in the open air.
    During this process, the oxygen absorber package will get hot. This is normal.
    However, if you leave the oxygen absorbers in the open air too long they will get hot before you seal them in Mylar bags and they may not work.

  • When you are sealing your bags, try to press all the air out of them before sealing.

  • There should be no folds in the seal of your bags. If you seal a fold, it likely will allow air in and spoil the material in the package.

SAFE USE OF FREEZE DRYERS & PUMPS

  1. Harvest Right oil-sealed vacuum pumps and oil-free pumps are only to be used with foods and organic materials that are not harmful when swallowed or when vapors coming from those materials are also not harmful when inhaled.
    a. Harvest Right expressly warns users of its freeze dryers and vacuum pumps to not use them for any purposes other than freeze-drying food or other healthy, non-toxic materials. Harvest Right accepts no responsibility for such acts whether intentional or not.
    b. If someone uses the pump for freeze-drying anything with harmful chemicals in it, the freeze dryer and vacuum pump warranties are breached and no longer valid. Harvest Right accepts no liability for these acts and it is understood by both the customer and
    Harvest Right the customer knowingly performs these acts at the risk of their own health and wellbeing; and that the customer accepts responsibility for all such acts.

  2. Harvest Right freeze dryers, in conjunction with their vacuum pumps, must be used in well-ventilated rooms. When using an oil pump, vaporization of oil is not expected at ambient temperatures. The oil is not expected to cause inhalation-related disorders under anticipated conditions of use.

  3. Harvest Right freeze dryers and vacuum pumps must be operated correctly as described in Harvest Right’s instruction documents and user manuals. When in use, drain valves must be closed, doors latched securely (with no obstructions between the doors and the door gaskets), and hoses connecting pumps to the freeze dryer must be connected properly. The users of the freeze dryers have the responsibility of ensuring that there are no leaks in the system whatsoever.

  4. All Harvest Right instructions for operating the freeze dryer are to be explicitly followed by the user/customer. Harvest Right accepts no responsibility for acts that breach its instructions.
    a. If there are leaks in the system, the freeze dryer(s) will report that there is a vacuum error. Users of Harvest Right freeze dryers understand that they should respond quickly and responsibly to these messages.

  5. When draining oil from vacuum pumps that use oil, the user must not tilt the vacuum pump so far forward that oil pours into and/or fills the oil demister/ filter. Doing this can cause some oil to be in the demister which could then cause oil vapor to come out of the filter while operating. It should be noted that the oil demister used on Harvest Right’s Premier Oil Pump has a drain in it that allows oil to drain back into the vacuum pump. However, if the white filter inside the oil demister becomes saturated with oil, it is important to wash and clean it with warm soapy water and then allow it to dry before using it again.

  6. Freeze dryers should be allowed to run automatically. Those customers who take shortcuts and skip standard cycles such as “Freezing,” “Vacuum Freeze,” “Drying,” and “Final Dry” do so at the peril of damaging their food and freeze dryer equipment. Harvest Right accepts no responsibility for intentional or unintentional acts performed by customers that circumvent Harvest Right’s automatic “freeze-dry” process(s).

  7. Do not stand in puddles of water when using the freeze dryer.

  8. Do not allow water to get on electric plugs and receptacles.

  9. Do not touch exposed wires or any other components inside the freeze dryer while the unit is plugged into an electrical outlet.

  10. Do not sleep in a room or other location where a freeze dryer and vacuum pump are being used.

  11. On the back of the freeze dryer, there is an electrical outlet for the vacuum pump to connect to. Do not plug anything else into that outlet.

  12. Do not run the freeze dryer with the side panels removed. This may be an electrical hazard.

  13. Do not add Teflon tape or other materials to hose joints.

  14. Do not overfill oil vacuum pumps with oil and be sure to follow oil changing guidelines explicitly.

  15. Keep the interior of the vacuum chamber and the shelves clean. Wash with warm soapy water. Do not place the shelf unit in a dishwasher. Wash it and rinse it by hand.

  16. It is important to regularly pour a safe cleaning agent down the drain line to keep it clean and prevent mold and bacteria from growing inside it.

  17. Make sure the drain hose is out of the water bucket before venting the vacuum chamber.

  18. Make sure that the material to be packaged is completely dry.

  19. Food with animal fat may go rancid. Always freeze-dry completely. Make sure a good oxygen absorber is in the package and that the Mylar bag is well sealed. Once opened, the material is refrigerated or used immediately.

  20. Harvest Right is not responsible for your use of the freeze dryer. Harvest Right is not responsible for the material that has gone “bad” for any reason including lack of dryness, improper storage techniques, and materials.
